| 7:30 a.m. | News (Business Wire): Silence Therapeutics Announces Positive Topline Results from Phase 2 SANRECO Trial of Divesiran in Polycythemia Vera, Supporting its Potential Best-in-Class Profile |
| 7:30 a.m. | First trade 20% above the previous close of 11.95 |

| 7:40 a.m. | High of the day to the close, 21.07 |
| 9:30 a.m. | The open: 16.62, up 39.1% from the previous close |
| 3:59 p.m. | Last trade before the 4:00 p.m. close, 15.43, 26.8% below the high |
The shape is a fixed rule, not a judgement: gapped 10% or more at the open, ran 10% or more from the open to the high, and faded if it gave back 30% or more of that move by the close.
The day in numbers
- From news to the move: the first trade 20% above the previous close came less than a minute after the latest news item before it (Business Wire, 7:30 a.m.).
- Volume, from the one-minute bars: 4.28 million shares before the 9:30 a.m. open (45%), 1.11 million in the first 30 minutes (12%), and 4.12 million in the rest of the day to 8 p.m. (43%).
- In our recaps, this is the only day SLN met the small-cap rule.
